catalytic system for β-alkylation of lactic acid with primary alcohols has been developed. In the presence of nickel(II) acetate tetrahydrate [Ni(OAc)2(H2O)4] and base, lactic acid reacts with primary alcohols to afford the corresponding coupled α-hydroxycarboxylicacids in good to excellent yields via a hydrogentransferprocess without any hydrogen acceptor or hydrogen donor.
